Nonanedioic acid, polymer with 2,2-bis(hydroxymethyl)-1,3-propanediol and 4,5,6,7,8,8-hexachloro-3a,4,7,7a-tetrahydro-4,7-methanoisobenzofuran-1,3-dione, (9Z)-9-octadecenoate (CAS 65970-25-4), molecular formula C9H2Cl6O3C18H34O2C9H16O4C5H12O4 and molecular weight 977.65 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Nonanedioic acid, polymer with 2,2-bis(hydroxymethyl)-1,3-propanediol and 4,5,6,7,8,8-hexachloro-3a,4,7,7a-tetrahydro-4,7-methanoisobenzofuran-1,3-dione, (9Z)-9-octadecenoate (C9H2Cl6O3C18H34O2C9H16O4C5H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 977.65 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
